Hello! Does anyone know or know where I can find estimates about the click-through rates of price comparison sites. We're planning to include a price comparison feature in a new website and, assuming that our site receives traffic (we think the its other features will be compelling & unique), we would like to estimate what percent of that traffic we can expect to actually click through? I do understand that click-through rates & cost per click vary by product category as well as site quality etc. TIA
